The latest MOT test on 6 August 2025 resulted in a pass, although it noted an advisory for a binding offside rear service brake. Reviewing the long-term history, the maintenance trend appears generally stable, though there is a recurring theme of rubber component degradation and braking system wear. While the vehicle enjoyed a period of clean tests between 2019 and 2020, the reappearance of brake-related concerns in the most recent inspection suggests that the braking system is once again requiring attention, following a historical pattern that includes a dangerous failure for brake efficiency back in 2008. The recorded mileage of 86,878 miles is very low for a vehicle that is approximately 37 years old, averaging roughly 2,348 miles per year. This usage profile strongly suggests the car has been kept as a leisure vehicle or has spent significant periods in storage. While this results in less mechanical wear on the engine and gearbox, low-mileage vehicles of this age are often susceptible to deterioration caused by inactivity. This typically manifests as the perishing of rubber seals, the accumulation of moisture in the braking system, and the degradation of fluids that should be replaced based on a calendar schedule rather than mileage. Buyers should focus their mechanical inspection on the braking and suspension systems. The recent advisory for a binding rear brake, coupled with previous records of corroded brake pipes and deteriorated hoses, indicates a need to check for hydraulic leaks or seized calipers. During a test drive, the driver should feel for any uneven braking or a spongy pedal and listen for knocks or clunks over bumps, which would indicate that the historically worn shock absorber and anti-roll bar bushes have further deteriorated. The recurring nature of these suspension advisories suggests that the rubber bushings have likely hardened with age and may require a comprehensive refresh to ensure roadholding stability. Given the low annual mileage, a detailed physical assessment of age-related wear is essential. Inspect all tyre sidewalls for cracking or perishing, as tyres often expire due to age before the tread is worn. Check the brake discs for heavy surface corrosion and verify the health of the 12V battery, which can suffer from deep discharge during long periods of standing. It is also critical to verify the service history to ensure that engine oil, coolant, and brake fluid have been changed according to time intervals. Finally, a close inspection of the exhaust flanges and chassis is recommended to ensure that the corrosion noted in previous years has been properly addressed and has not compromised the structural integrity of the vehicle.
